Fuzzing the brain: Automated stress testing for the safety of ML-driven neurostimulation

We propose a systematic, quantitative approach to detect and characterize unsafe stimulation patterns in ML-driven neurostimulation systems.

Perceptual learning of prosthetic vision using video game training

We evaluated whether gamified training improves compensation for population-coding distortions in sight recovery by testing transfer of learning between a dichoptic object recognition task and a filtered version of Fruit Ninja, finding no significant transfer and suggesting limited generalizability of gamification-based rehabilitation.

Simulated prosthetic vision confirms checkerboard as an effective raster pattern for epiretinal implants

Using an immersive VR system, we systematically evaluated two behavioral tasks under four raster patterns (horizontal, vertical, checkerboard, and random) and found checkerboard raster to be the most effective.

Assistive technology use in domestic activities by people who are blind

We present insights from 16 semi-structured interviews with individuals who are either legally or completely blind, highlighting both the current use and potential future applications of technologies for home-based iADLs.

Aligning visual prosthetic development with implantee needs

Our interview study found a significant gap between researcher expectations and implantee experiences with visual prostheses, underscoring the importance of focusing future research on usability and real-world application.

Axonal stimulation affects the linear summation of single-point perception in three Argus II users

We retrospectively analyzed phosphene shape data collected form three Argus II patients to investigate which neuroanatomical and stimulus parameters predict paired-phosphene appearance and whether phospehenes add up linearly.

Explainable machine learning predictions of perceptual sensitivity for retinal prostheses

We present explainable artificial intelligence (XAI) models fit on a large longitudinal dataset that can predict perceptual thresholds on individual Argus II electrodes over time.

Stress affects navigation strategies in immersive virtual reality

We used immersive virtual reality to develop a novel behavioral paradigm to examine navigation under dynamically changing, high-stress situations.

Retinal ganglion cells undergo cell type--specific functional changes in a computational model of cone-mediated retinal degeneration

We present a biophysically detailed *in silico* model of retinal degeneration that simulates the network-level response to both light and electrical stimulation as a function of disease progression.

A systematic review of extended reality (XR) for understanding and augmenting vision loss

We present a systematic literature review of 227 publications from 106 different venues assessing the potential of XR technology to further visual accessibility.
